RT Conference Proceedings T1 Co-planar PET/CT for small animal imaging A1 Vaquero López, Juan José A1 Redondo, Santiago A1 Abella García, Mónica A1 Pascau González-Garzón, Javier A1 Sánchez, Javier A1 Vicente, Esther A1 Soto Montenegro, Mª Luisa A1 Desco Menéndez, Manuel A1 Lage Negro, Eduardo AB A small animal PET/CT system based on a common rotating gantry is proposed. The PET detection subsystem is composed of two detector modules based on MLS arrays andfour flat panel type PS PMT. The CT subsystem consists in a micro focus X ray tube and a semiconductor X ray detector.Space for opposed PET detectors and the CT scanner have been allocated on the same plane in such a way that the trans axialand axial centers are common for both systems. Shielding elements have been placed around the detectors to avoid crossmodality contamination. The gantry can rotate 370 degrees to provide complete data sets for the CT image reconstructionalgorithm that is based on the cone beam geometry. PET image reconstruction is implemented using FBP (2D and 3D) andOSEM. Sequential acquisition protocols minimize the scanduration, and CT information can be used to implement PETimaging corrections. The coplanar configuration of this systemprovides intrinsically co registered data sets, and it is notnecessary to reposition the animal to perform any modalityimaging, avoiding undesired animal or additional accessories movements. An additional advantage is the compactness of the system that saves space and allows a direct visual monitoring of the animal during the scan PB IEEE SN 0-7803-9221-3 SN 1082-3654 YR 2005 FD 2005-10 LK https://hdl.handle.net/10016/12138 UL https://hdl.handle.net/10016/12138 LA eng NO Proceeding of: 2005 IEEE Nuclear Science Symposium Conference Record, Puerto Rico, October 23 - 29, 2005 NO Part of this work is founded by the IM3 network (G03/185 Ministerio de Sanidad), with grants from the Ministerio de Educación y Ciencia, project TEC2004-07052-C02-01, andMinisterio de Industria, Turismo y Comercio project FIT-330101-2004-3.
